Anyway here is the question:
"Let X1 , . . . , Xn be a random sample from a Geom (θ) distribution, where θ is a single unknown
parameter. State the value of E(X ; θ) and hence find the method of moments estimator of the
unknown parameter θ."
Now i know that E( X;theta) is 1/theta but i dont know where to go from there....
